CHARLES H. COLBY, OF BROOKLYN, NEW YORK, ASSIGNOR TO J. COLBY & COJ, OFSAME PLACE.

OPERATORS SEAT.

SPECIFICATION forming part of Letters Patent No. 478,987, dated July 19,1892.

Application filed September 1'7, 1891- Serial No. 405,952. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES H. COLBY, a citizen of the United States,residing in Brooklyn, in the county of Kings and State of New 5 York,have invented a certain new and-useful Improvement in Operators Seats,of which the following is a specification.

This invention relates particularly to seats for operators of sewing andother hand-con- IO trolled machines, although it is also advantageouslyapplicable in various other situations, as at the counters, tables, andbenches used in other occupations.

The objects of my invention areto provide for conveniently raising andlowering such seats for use and for putting them out of the way when notin use, and also to simplify, strengthen, and otherwise improve theirconstrnction.

The invention consists of a novel construction and combination of parts,substantially as hereinafter described and as claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which Figure 1 is a plan of one seat and part of another applied to asewing-machine table in accordance with my invention. Fig. 2 is a sidesectional elevation of the same on the line X X, Fig. 1. Fig. 3 is afront sectional elevation on the line Y Y, Fig. 2.

Like letters of reference designate corresponding parts in the severalfigures.

A designates part of a sewing-machine ta- '3 5 ble, and B a rigid leg orstandard of the same located at one side of the machine.

In applying my improved operators seat to such a table the standard B ispreferably formed in advance integrally with upper and 0 lower bracketsC and D, which are formed with end socket-bearings C and D, opening,respectively, downward and upward. The bearings C and D are adapted toreceive loosely the upper and lower ends of an up- 5 right pivot-bar E,and are so placed that the Fig. 3.

said pivot-bar will be slightly inclined upward and laterally toward themachine at which the operator is to sit, as best shown in On theinclined pivot-bar E is fitted to slide up and down a thick sleeve F,provided with a binding-screw G, to work against the bar E and formedintegrally with a stiff horizontal arm H, which normally curves outwardand laterally in the direction of the incline of the pivot-bar-that' is,toward the front of the machine before which the operator is to sit. Onthe extremity of the arm H is formed, by preference, integrally the seatJ, facing the machine. The seat J can thus be swung, with the arm H, onthe pivot-bar E to any desired position for use with respect to themachine, and can also be instantly adj usted, with the arm H, up anddown the pivot-bar E and secured in position thereon by thebinding-screw G. 6 5

When the seat-J is not in use, it, together with the arm H, will swingby gravity. under the table A, owing to the slant of the pivotbar E, andwill thus remain out of the Way until used again. The described curve ofthe arm l-I causes it to join the seat at the side thereof, and thus bewholly out of the way of the operators legs, and also carries the seatmore completely out of the way when not in use.

I claim as my invention The combination, substantially as hereinbeforeset forth, of a table, a support thereof having upper and lowerbearings, the line of which is somewhat inclined from the Vertical, abarpivoted at its upper and lower ends to said bearings,- a sleevecarryinga set-screw, fitted to slide up and down on said pivot-bar, andan arm rigidly attached to said sleeve and carrying at its outer end anoperators seat J.
